    Google Earth is a computer program that renders a 3D representation of Earth based primarily on satellite imagery. The program maps the Earth by superimposing satellite images, aerial photography, and GIS data onto a 3D globe, allowing users to see cities and landscapes from various angles. Users can explore the globe by entering addresses and ...

    The sensor on weather satellites that picks up the data transmitted in HRPT is referred to as an Advanced Very High Resolution Radiometer (AVHRR). [1] The working frequency band for HRPT is L Band at 1.670–1.710 GHz and the modulation types are BPSK and QPSK. [2] On NOAA KLM satellites the transmission power is 6.35 Watts, or 38.03 dBm. [3]
